Flickering tach
 
My 85 GS tack is flickering but the engine rpms are steady. I would think this could be an electronic issue?
I attached a video of the tack movement. Does anyone know what’s causing this?

Check the connection of the 2 prong connector to the alternator, another user here had an issue like this and cleaning it and plugging securely fixed it. Also make sure the trailing coil tach connection is clean and well connnected as the tach gets its pulse from the trailing on series 3 7s.
